Abstract
The utility model discloses a kind of driving machine travel unit, there is walker, expansion tightening wheel, driving wheel and track assembly, also comprise and be loaded on the leg member that described walker sidewall can penetrate underground.Described leg member comprises supporting leg body, taper pin nail is equipped with in the bottom of supporting leg body, one end of supporting leg body upper part helps power cylinder by the first hinge, the other end of power-assisted oil cylinder is connected with the side walls hinged of described walker by the second bearing pin, the other end of described supporting leg body upper part is connected with the side walls hinged of described walker by the 3rd bearing pin, and the cross section that described first bearing pin, the second bearing pin and the 3rd bearing pin surround is triangle.Adopt the driving machine travel unit of said structure, when development machine carries out excavation operation in heavy grade tunnel, the taper pin nail of described supporting leg body bottom portion can penetrate underground, effectively can prevent the downslide phenomenon of development machine under heavy grade environment during operation, effectively can stop the potential safety hazard because development machine produces when heavy grade environment work.
Description
Technical field
The utility model relates to a kind of driving machine travel unit, especially relates to a kind of driving machine travel unit adapting to heavy grade operation.
Background technology
Driving machine travel unit mainly comprises walker, expansion tightening wheel, driving wheel and track assembly, and traditional development machine is in large descending situation, and brake is unstable, easily causes danger; When large upward slope, the tractive force of walking is not enough, and the danger of skidding or gliding also can occur complete machine sometimes.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of development machine and can not produces when heavy grade carries out excavation operation and glide and cause the driving machine travel unit of potential safety hazard.
For solving the problems of the technologies described above, the utility model driving machine travel unit, has walker, expansion tightening wheel, driving wheel and track assembly, also comprises and is loaded on the leg member that described walker sidewall can penetrate underground.
As improvement of the present utility model, described leg member comprises supporting leg body, taper pin nail is equipped with in the bottom of supporting leg body, one end of supporting leg body upper part helps power cylinder by the first hinge, the other end of power-assisted oil cylinder is connected with the side walls hinged of described walker by the second bearing pin, the other end of described supporting leg body upper part is connected with the side walls hinged of described walker by the 3rd bearing pin, and the cross section that described first bearing pin, the second bearing pin and the 3rd bearing pin surround is triangle.
Adopt the driving machine travel unit of said structure, when development machine carries out excavation operation in heavy grade tunnel, can by controlling described power-assisted oil cylinder, the piston rod of power-assisted oil cylinder is extended, now described this cognition of supporting leg with the second bearing pin for the center of circle is rotated counterclockwise, the taper pin nail of supporting leg body bottom portion can penetrate underground, effectively can prevent the downslide phenomenon of development machine under heavy grade environment during operation, effectively can stop the potential safety hazard because development machine produces when heavy grade environment work.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model driving machine travel unit.
Fig. 2 is the I place structure enlarged diagram in Fig. 1, shows the structure of the leg member be loaded on walker sidewall.
Detailed description of the invention
See Fig. 1, Fig. 2, driving machine travel unit of the present utility model, has walker 1, expansion tightening wheel 2, driving wheel 3 and track assembly 4, also comprises and is loaded on the leg member that described walker 1 sidewall can penetrate underground.Described leg member comprises supporting leg body 5, taper pin nail 6 is equipped with in the bottom of supporting leg body 5, the one end on supporting leg body 5 top is hinged with power-assisted oil cylinder 8 by the first bearing pin 7, the other end of power-assisted oil cylinder 8 is connected with the side walls hinged of described walker by the second bearing pin 9, the other end on described supporting leg body 5 top is connected with the side walls hinged of described walker by the 3rd bearing pin 10, and the cross section that described first bearing pin 7, second bearing pin 9 and the 3rd bearing pin 10 surround is triangle.
